Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.

SOLH 50 series flameproof pilot solenoid valves cover two models: 50-VFE 5/2 spool valve and 50-VPE 3/2 poppet valve. Certified Ex d Ⅱ BT4, CCC, TIIS & IEC with IPX6 protection, they apply to Zone 1 & Zone 2 flammable and explosive environments such as lithium coating, chemical, painting and oil & gas workshops. Both share interchangeable 3.5W low-power flameproof coils and housings, while their manifold bases are non-interchangeable. 50-VFE requires 0.15MPa differential pressure and only works for positive-pressure double-acting cylinder circuits, incompatible with vacuum. 50-VPE features zero-pressure startup, stable under full vacuum down to -101.2kPa and automatic pressure relief upon power loss for vacuum handling and single-acting cylinders. Lubrication-free design allows single threaded mounting or multi-station manifold valve island assembly with certified flameproof wiring fittings, providing safe standard pneumatic switching for explosion-proof industrial production lines.

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.
